Probing the charged nature and ion-exclusion mechanism of fluorine-enriched non-ionogenic polyamide derived thin film composite nanofiltration membranes

A thin film composite (TFC) nanofiltration (NF) membrane comprising a novel fluorine-enriched polyamide (FPA) as a skin layer polymer has been developed by in situ interfacial polycondensation between a cyclo-aliphatic diamine monomer, piperazine, and an acyclic fluorodiacyl chloride monomer, tetrafluorosuccinyl chloride. Instrumental investigations carried out by FTIR and XPS showed that the structure of FPA is devoid of intra- as well as inter-molecular H-bonds, which seems to be a rare finding in NF type membranes with decent performances. Stereoelectronic effects of the FPA structure, owing to the configurational mobility of polymer chains, electron-withdrawing ability of fluorine and lack of cohesive non-covalent type interactions, strongly influenced the surface morphology, topography and hydrophilicity of the TFC-NF membranes. The active skin layer of the membranes exhibited uniform charge-atmosphere in spite of not having any fixed charged groups in the polymer structure constituting it. Zeta potential measurement of the membranes revealed low values (-4.4 to -7 mV), indicating their low surface charge. However, a high Donnan-exclusion was observed towards a solute with multivalent anion (Na2SO4, solute rejection: 87-93%) as opposed to that with monovalent anion (NaCl, solute rejection: 23-26%), with a solvent flux as high as 54 L m(-2) h(-1) at 15 bar transmembrane pressure. The current class of TFC-NF membranes with unique physicochemical attributes thus provides a promising scope for a variety of nanofiltration applications.

Novel mTORC1 Inhibitors Kill Glioblastoma Stem Cells

Glioblastoma (GBM) is an aggressive tumor of the brain, with an average post-diagnosis survival of 15 months. GBM stem cells (GBMSC) resist the standard-of-care therapy, temozolomide, and are considered a major contributor to tumor resistance. Mammalian target of rapamycin Complex 1 (mTORC1) regulates cell proliferation and has been shown by others to have reduced activity in GBMSC. We recently identified a novel chemical series of human-safe piperazine-based brain-penetrant mTORC1-specific inhibitors. We assayed the piperazine-mTOR binding strength by two biophysical measurements, biolayer interferometry and field-effect biosensing, and these confirmed each other and demonstrated a structure-activity relationship. As mTORC1 is altered in human GBMSC, and as mTORC1 inhibitors have been tested in previous GBM clinical trials, we tested the killing potency of the tightest-binding piperazines and observed that these were potent GBMSC killers. GBMSCs are resistant to the standard-of-care temozolomide therapy, but temozolomide supplemented with tight-binding piperazine meclizine and flunarizine greatly enhanced GBMSC death over temozolomide alone. Lastly, we investigated IDH1-mutated GBMSC mutations that are known to affect mitochondrial and mTORC1 metabolism, and the tight-binding meclizine provoked ‘synthetic lethality’ in IDH1-mutant GBMSCs. In other words, IDH1-mutated GBMSC showed greater sensitivity to the coadministration of temozolomide and meclizine. These data tend to support a novel clinical strategy for GBM, i.e., the co-administration of meclizine or flunarizine as adjuvant therapy in the treatment of GBM and IDH1-mutant GBM.

Enhanced oxidative degradation of norfloxacin using peroxymonosulfate activated by oily sludge carbon-based nanoparticles CoFe2O4/OSC

In this study, oily sludge (OS) was pyrolyzed into an environmentally friendly OS carbon (OSC) material, which was used as the carrier of CoFe2O4 nanoparticles to prepare a heterogeneous catalyst CoFe2O4/OSC, and it was used to catalyze the degradation of norfloxacin (NFC) by peroxymonosulfate (PMS). X-ray diffraction (XRD) and transmission electron microscope (TEM) characterization results show that CoFe2O4/OSC had a spinel structure under high temperature pyrolysis conditions. The effects of initial pH, PMS dosage, catalyst dosage, and temperature on NFC degradation efficiency were also studied. Under a temperature of 25 degrees C, an initial pH of 7, a catalyst amount of 0.5 g/L, and a PMS dosage of 0.8 mM, the reaction rate constant reached 0.051 min(-1), and the degradation efficiency and total organic carbon of NFC reached 90.8% and 62%, respectively, within 60 min. Trace amounts of Co and Fe ions were leached from the system (both less than 30 mu g/L). After ten cycles, the degradation efficiency of NFC decreased to 69.8%. Radical quenching experiments, electron paramagnetic resonance, and X-ray fluorescence spectroscopy characterization proved that free-radical ((OH)-O-center dot, SO4 center dot-, and O-2(center dot-)) and nonradical (O-1(2)) active species were present in the system. Moreover, the CoFe2O4/OSC/PMS system involved the participation of two pairs of redox couples (Fe(II)/Fe(III) and Co(III)/Co(II)). Results from matrix-assisted laser desorption ionization time-of-flight mass spectrometry and ion chromatography proved that the main oxidation pathways of NFC were formed through the fragmentation of heterocycles, defluorination of benzene rings, decarboxylation reactions, and piperazine ring-opening process. At the same time, NFC was eventually oxidized to fluoride. This study provides potential for the resource utilization of OS and the application of sludge-type catalysts in PMS-activated oxidation systems.

Advancement of ammonia-based post-combustion CO(2 )capture technology: Process modifications

Aqueous ammonia (NH3)-based capture process has the potential to simultaneously remove NOx/SO2/CO2 pollutants at low cost, but conventional NH3-based process suffers high NH3 slip, high energy consumption and high capital investment. The present study aims to advance the NH3-based scrubbing technology to overcome these technical issues. We used inter-cooled CO2 absorber to mitigate the NH3 emission and enhance CO2 absorption, while employed advanced flash stripper configuration to significantly decrease the absorbent regeneration duty. We also proposed an effective NOx/SO2 removal process by utilizing the slipped NH3 for multi-pollutant emission control. A validated model was used to gain insight into the techno-economic performance of this advanced NH3-based NOx/SO2/CO2 removal process, and important process parameters such as absorption temperature, NH3 concentration and flue gas NOx/SO2 concentrations were investigated in detail. The results indicate that the advanced NH3 process enabled great capital saving by 23% and energy saving by 42%, resulting in a low CO2-avoided cost of USS44.3/t CO2, which is 42.8% lower than the baseline NH3 process.

Novel piperazine-2,5-dione analogs bearing 1H-indole: Synthesis and biological effects

In this work, a series of novel piperazine-2,5-dione derivatives bearing indole analogs (2a-2q) was designed and synthesized. The synthesized compounds were characterized by IR, H-1 NMR, C-13 NMR spectroscopy, and ESI-MS. They were then evaluated for their anti-depressant, anti-inflammatory, and analgesic activities in vivo. The experimental results revealed that all the compounds showed clear anti-depressant, anti-inflammatory, and analgesic effects at a dose of 10 mg/kg. Among them, compounds 2e and 2q exhibited the best anti-depressant effects (the percent decreases in the duration of immobility were 70.2% and 71.2%, respectively), which were similar to that of fluoxetine (67.9%) in the forced swim test. Additionally, compounds 2e and 2q also displayed good anti-inflammatory and analgesic activities. Literature reports have highlighted the anti-inflammatory and analgesic effects of anti-depressant drugs, suggesting that they may have a similar mechanism of action. Therefore, further studies to investigate the possible mechanisms of action of compounds 2e and 2q are warranted.

The interfacial degradation mechanism of polymer:fullerene bis-adduct solar cells and their stability improvement

Although fullerene bis-adducts have been widely used in polymer solar cells for their high LUMO energy level and good performance, the degradation behavior of this class of solar cells has not been well understood. In this paper, the performance and stability of the solar cells based on P3HT:fullerene bis-adducts, including bis-PC61BM and ICBA, were systematically investigated. Different from the P3HT:PC61BM cell, these bis-adduct based cells showed fast open circuit (V-OC) and fill factor (FF) decays. The partial recovery of V-OC and FF of the aged cells by renewing the MoO3/Al electrode indicated that degradation at the photoactive layer and MoO3 interface is the main reason for V-OC and FF decays. The X-ray photoelectronic spectroscopy analysis confirmed that under light illumination, Mo6+ of MoO3 is partially reduced to Mo5+. By inserting a thin layer of C-60, both MoO3 reduction and performance decays are slowed down, confirming that photoreduction of MoO3 by P3HT is the degradation mechanism for P3HT:bis-PC61BM cells. Finally, we found that doping a polymer:fullerene bis-adduct layer with piperazine increases the fullerene content on the surface of the photoactive layer, which consequently lowers the reduction of Mo6+ and improves the stability of the solar cells. This work gives a detailed understanding of the interfacial degradation of PSCs and provides effective solutions, which has important guiding significance for improving the stability of different types of polymer solar cells.

Immobilized piperazine on the surface of graphene oxide as a heterogeneous bifunctional acid-base catalyst for the multicomponent synthesis of 2-amino-3-cyano-4H-chromenes

Immobilized piperazine on the surface of graphene oxide (piperazine-GO) is synthesized and characterized by different methods such as FT-IR, solid-state(29)Si{H-1} and(13)C{H-1} CP/MAS NMR, elemental analysis, TGA, TEM, FE-SEM, XPS, and TPD. Subsequently, it is used as a heterogeneous bifunctional acid-base catalyst for the efficient multicomponent reaction of malononitrile, different active compounds containing enolizable C-H bonds and various aryl/alkyl aldehydes in aqueous ethanol. A wide variety of 2-amino-3-cyano-4H-chromenes are synthesized in the presence of this heterogeneous catalyst in good to high yields and with short reaction times. The catalyst is easily separated and reused for at least six times without significant loss of activity. The acidic nature of GO improves the catalytic activity of the supported piperazine and also provides heterogeneity to the catalyst. Use of aqueous ethanol as a green solvent, high turnover numbers (TON), facile catalyst recovery and reuse, simple work-up and generality of the method make this protocol an environmentally benign procedure for the synthesis of the title heterocycles.

Serotonergic-linked alterations of aggression of the crayfish

Current theory suggests that aggressive behavior in the crayfish is largely modulated and regulated by the neurotransmitter serotonin (5-HT). To test this theory that links serotonin to aggression, we performed a series of drug treatments using various serotonin-related chemicals to measure their effects on subsequent aggressive behavior. Treatments included serotonin, the serotonin precursor tryptophan, agonists: 1-(3-chlorophenyl) piperazine (m-CPP) and 5-Carboxy, an antagonist: cinanserin, and a serotonin receptor specific neurotoxin: 5,7-dihydroxytryptamine creatinine sulfate (5,7-DHT). Significant increases in aggression ofFaxonius rusticuscrayfish were observed when injected with serotonin and both agonists, however no decrease in aggression occurred with the antagonist. Crayfish injected with the agonist m-CPP increased aggression but did not directly confer success in fights. Our data support the current literature that the internal aggressive state of crayfish is altered by serotonin and its agonist/antagonists, however it does not on its own improve the aggressive fighting response and/or dominance status.

Copper(II) Complexes with Tetradentate Piperazine-Based Ligands: DNA Cleavage and Cytotoxicity

Five-coordinate Cu(II) complexes, [Cu(L-n)X]ClO4/PF6, where L-n = piperazine ligands bearing two pyridyl arms and X = ClO4- for L-n = L-1 (1-ClO4), L-2 (2-ClO4), L-3 (3-ClO4), and L-6 (6-ClO4) as well as [Cu(L-n)Cl]PF6 for L-n = L-1 (1-Cl), L-4 (4-Cl), and L-5 (5-Cl) have been synthesized and characterized by spectroscopic techniques. The molecular structures of the last two complexes were determined by X-ray crystallography. In aqueous acetonitrile solutions, molar conductivity measurements and UV-VIS spectrophotometric titrations of the complexes revealed the hydrolysis of the complexes to [Cu(L-n)(H2O)](2+) species. The biological activity of the Cu(II) complexes with respect to DNA cleavage and cytotoxicity was investigated. At micromolar concentration within 2 h and pH 7.4, DNA cleavage rate decreased in the order: 1-Cl approximate to 1-ClO4 > 3-ClO4 >= 2-ClO4 with cleavage enhancements of up to 23 million. Complexes 4-Cl, 5-Cl, and 6-ClO4 were inactive. In order to elucidate the cleavage mechanism, the cleavage of bis(4-nitrophenyl)phosphate (BNPP) and reactive oxygen species (ROS) quenching studies were conducted. The mechanistic pathway of DNA cleavage depends on the ligand’s skeleton: while an oxidative pathway was preferable for 1-Cl/1-ClO4, DNA cleavage by 2-ClO4 and 3-ClO4 predominantly proceeds via a hydrolytic mechanism. Complexes 1-ClO4, 3-ClO4, and 5-Cl were found to be cytotoxic against A2780 cells (IC50 30-40 mu M). In fibroblasts, the IC50 value was much higher for 3-ClO4 with no toxic effect.
